s calma (ci. 251-4) This invention relates to improvements in air conditioning mechanism. y

'Ihe primary object of thepresent invention is to provide an air conditioning mechanism in the form of a unit which may be conveniently moved within a home or other establishment where it is to be used and which is so designed that it may function as an' air heater or an air cooler, as may be desired.

ln Another object of the invention is to provide an air conditioning unit employing water as a heating or cooling medium for effecting or bringing about an increase or decrease in the temperature of the air of a room in which the unit is installed, convenient means being made use of for shunti'ng the circulation of the water through a temperature raising or temperature reducing unit whichvforms a part of the mechanism.

The invention has for a morespe'cic object the provision of a mechanism for regulating the temperature of the air in a room by the process of circulating heated water through heat transfer tubes between which air is blown, when an increased temperature in a room is desired or circulating refrigerated water through said heat transfer tubes when a decreased temperature in a room is desired.'

The invention broadly comprises 'a mechanism consisting of two distinct parts, one of which '30` comprises a series of water tubes between which,

air may be forced and the other consisting of a rei'rigerating chamber through which water may be passed to be circulated through said tubes, whereby the water after being passed 35 through the refrigerating chamber andreduced in temperature will operate to reduce the temperature of the'surrounding atmosphere 'as itv iiows through said tubes and absorbs heat from the air driven vbetween the tubes.

'40 The invention wm be best understood 'from a consideration of the following detailed description taken in connection-with the accompanying drawings forming part of-this speciiication, with is not to be coniined to strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings: v

Figure 3 is a sectional lview taken on the' line 3- -3ofFigure2. l

Figure 4 is a sectional view taken on the line 5 4-4 of Figure 2.

Figure-5 is asectional view on an .enlarged scale on theline 5--5 of Figure 1.

Referring'now more particularly to the drawings,`the numeral I generally designates a housf' 10y ing for a blower by means of which air is circu lated through the hereinafter described'structure so that the necessary circulation of air in a room or building may be obtained. This housing encloses fan blades 2 of a suitable construc- 15- -tion and has the upwardly directed outlet conoutlet for the blower, thefair being taken in through the opening 5 in the side of the casing,- in the4 usual manner. 'Ihe fan 2 is mounted upon 20 the shaft 6 which, at'one side of the housing I, carries a pulley wheel 1, which is connected by a belt 8 with the pulley wheel 9 of a water pump I0. At the opposite side of the blower housing the shaft 6 carries a suitable pulley II for con- 2'5 -necting a drivingy motor I2 withthe fan shaft through the medium of a belt I3.

'I'he bell 4 of the blower is connected in the opening Il in one sidey of the upper part of a casing, whichis indicated as a whole by the numeral I5. This casing is divided into an upper heat transfer chamber I6 and a lower refrigerating chamber I1. For convenience in describfing the general construction ofthe mechanism; and without intending to limit the form of the same in any manner, the casing may be set forth as. having the top and'bottom walls I8V and I9,

the vertical side walls 20 and the front and rear Y walls 2l and.`22,grespectively. Thus, it will'be apparent from reference to Figure 1 that the 40 opening Il is in the upperA half of the back wall ofthe casing. -Just below the opening Il, the casing is horizontally divided by the wall 23 which has. a central opening surrounded by the downturned iiange 2l for the purpose hereinafter de- 45 scribed.` The front wall 2I `opposite the opening I4 is provided with a plurality of apertures 25 orthis wall may be opened-or covered by screen, if desired, so long as air discharged into the chamber I6 from theconduit 3 may have free 50 passage through the chamber into the room from which'it was drawn into the fanvhousing I.

Extending across the upper part ofthe chamv ber I6 between the side walls 2l and in relatively closely spaced relation with the top .wall I8, is a wxtnmthnnmbernmmpornheremgemt s my n n n s m a w w w w mummm@. mdmwsnm n mm wwmwmmmmmnm mmmmmnmmmmmmm mw .mmmmwwm mgm .mwwwmmmmmmmmmdmmmmmu mmwmmmmmmmmm w m mm me www? wm a2 mumm .m Mwmmmmd mmm mmmhwm d mdmemwummwmmm Mm u eb tm. emhwaLm mmnwttwn. madam n s e mme o mu e m m mm m H. mmc mmmmwmomm m. m Mmmm Mmmm?. o Mmmm Mmmm @um wem.. mmmmmwmmmmmmmmmmmmmmmw mmmmmmmmmmmmmwmmmmmmwmm mmmwmmmmm um m. .wmmy #d M .,w u um mmmdmmmmmmmmmmmmmmmmwmwmmmmmwmMmmmwmmmmwmmmmmmmwmmmmmmm wwwmmmmmmmmmdmmmmm mwmwmx v mmmw we m M mmmmmmmmmmmwww@ mmmmmmmmmmmmmmmmm Mm mmwmmmmmmmmww .w m me m www m umm m m hmmm u u nu .um In. :un mwmmmmmi mhmmmmwmm mmmwmm mman u N m www m, wm. mmm... mmmmwmmzmmmwnmmmmwmmwmmwm wmemmmmm m m mam Md m mmmmumm ,M m M mmm mmm fm M m n :www M mm ,mm im mm @.mmmmmw m mi@ m mmm mmmmm Mmmmmmmmmmm M swam um mmm m h. u mm2 .mmmmmmmmwmmmr mim; www mm T tm 1Mb m m www mmmm m m m .m m u www.. m. m. m mmmmmmmmmmmmwmmmmmmwww?mmmmmmmwmmwmmmmmwwmwmmmmm as desired, and the control valve for the outlet i which it will then iowl over the sides into the troughs Gil and run down the screens Ato the bottom of the refrigerating chamber. It will be noted that4` due to the novel arrangement of the .vater circulating means in the refrigerant chamber, the water is carried downwardly through the.

chamber and in relatively close proximity to the refrigerant medium, which is exposed in the chamber so,that there will be a free circulation of air around it, but the water is not brought into contact with this medium. Thus the water passing through the refrigerant chamber circulates in the air in which the refrigerant medium is placed but does not now over or come into contact with the medium. The water will then be drawn by the pump I0 from the lower part of the i refrigerating chamber and passedup again to the receiver 31 to repeat the circuit. The receptacle 52 will,of course, contain a refrigerant medium or some other means will be employed for refrigerating the chamber l1 so that the water, las it passes through the refrigerating chamber, will be thoroughly chilled or, in other. words, will have the absorbed heat removed therefrom and will be recirculated through the tubes 34 toy absorb heat from the air blown over the tubes by the blower connected with the chamber` I6.y

From the foregoing, it will be readily seen that there has here been disclosed novel compact mechanism which will operate efficiently for the purpose of heating or cooling air in a room or building and which will operate with a minimum of expense as the. water used inthe system is made use of over and over again, thus reducing the .cost -of operation over those systems which are connected with a house water supply and which have fresh water passing through continuously.`
